Early or partial results. Treat as a signal, not a conclusion.
This is a completed registry record of a small interventional study comparing eccentric versus concentric exercise training in adolescents with obesity. No results are posted in this registry entry, and the study design, sample size, and publication status do not permit any inference about efficacy or safety.
Interventional, Randomized, Parallel, Single masking, Other purpose. Adolescents (12 to 17 Years Old), Obese (BMI>90th Percentile); age from 12 Years; to 17 Years. Intervention: Concentric cycling exercise (CON); eccentric cycling exercise (EXC). Compared with: Concentric cycling exercise training for 12 weeks at equivalent VO2 consumption.. n = 25. 1 site: France.

Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
Clinicians should not draw any conclusions about the effectiveness or safety of eccentric versus concentric exercise in adolescents with obesity from this registry record alone. Results must be published in a peer-reviewed venue before clinical guidance can be formulated.
This is a completed but unpublished registry record with no results posted; it describes the planned design and hypothesis of a small pilot study in adolescents with obesity.

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
What is missing. This record has no key findings. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT02925572). This is a study registration, not published results. Lead sponsor: University Hospital, Clermont-Ferrand. Recruitment status: COMPLETED. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 25 participants (ACTUAL). Conditions: Adolescents (12 to 17 Years Old), Obese (BMI>90th Percentile). Interventions: OTHER: Cycling exercises. Primary outcome measures: change in total body fat mass (Dual X ray Absorptiometry) , before and after the 12 weeks training program. Brief summary: Nowadays, eccentric exercise can be realized in a dynamic way with an ergocycle which permits eccentric (ECC) lower limbs contractions at a defined power output. With this type of ergometer, O2 consumption (VO2) in ECC is three fold lower than in concentric (CON) for the same power output. Consequently, ECC program could be used in chronic disorders with limited capacities, such as obesity. The investigators hypothesis that an eccentric training program, as it will induce higher mechanical constraints, would improve body composition, especially by reducing fat mass. This effect could be explained by an increased rest energy expenditure and a better improvement in biological parameters (particularly lipid profile and insulin-resistance) after ECC training (versus CON training). This study aims to compare the modification of fat mass after an ECC program versus a CON program at the same VO2.. The secondary goal is to assess the physiological mechanisms involved in the modification of body composition.
